davepwnt Posted July 11, 2006 Share Posted July 11, 2006 I like how you coloured it. Me and my friends made little hand held potato guns with axe, and small tubes. It's sick. Quote Link to comment Share on other sites More sharing options...
melodic Posted July 11, 2006 Share Posted July 11, 2006 WOAH THATS SICK!!! i like it :D Quote Link to comment Share on other sites More sharing options...
anyedie Posted July 11, 2006 Share Posted July 11, 2006 last year i made a cannon out of similar materals. I would suggest going by a local pawn shop and buying musket loading powder and using that as a propellent, gives a real nice cannon sound and lots of smoke and power! :twisted: Quote Link to comment Share on other sites More sharing options...
armadaender Posted July 11, 2006 Share Posted July 11, 2006 That was awesome! How far can it shoot? Quote Link to comment Share on other sites More sharing options...

Jordban Posted July 11, 2006 Author Share Posted July 11, 2006 I haven't gotten a chance to measure how far it shoots but I'd say 300 yards easy. Quote Link to comment Share on other sites More sharing options...

Jordban Posted July 12, 2006 Author Share Posted July 12, 2006 Haha, that would be pretty sick. Either that or a bore gun from like Turok 64! Quote Link to comment Share on other sites More sharing options...

okih-imus Posted July 12, 2006 Share Posted July 12, 2006 But after those first 100 yards (football field) who wants to see a barely visible 4 inch potato? And, if it was shot at a 45 degree angle and goes 300 yards then you're just watching the first 150 yards in reverse! :shock: 3 potatoes for 3 times the fun!

Jordban Posted July 12, 2006 Author Share Posted July 12, 2006 Very logical! I might have exagerated on the distance if a football field is 100 yards.. or 300 feet. Maybe closer to 150 yards or something. Quote Link to comment Share on other sites More sharing options...
Unrestricted Posted July 12, 2006 Share Posted July 12, 2006 you should take it off the stand and add a handle Quote Link to comment Share on other sites More sharing options...

Maybe closer to 150 yards or something. 150 yards is still damn good for a potato gun, most of my friends' only shot about 80 to 100. But most of those were built while intoxicated so I can see the large margin of error and faults in their designs. Quote Link to comment Share on other sites More sharing options...
okih-imus Posted July 13, 2006 Share Posted July 13, 2006 I've made a potato gun before...a half-assed one. I was very distraught to find that duct tape does fail sometimes :oops: Good thing no one was standing behind it at the time :shock: Quote Link to comment Share on other sites More sharing options...
Jordban Posted July 13, 2006 Author Share Posted July 13, 2006 Haha good stuff! Yeah adding a handle would be ideal! Quote Link to comment Share on other sites More sharing options...
dirty D Posted July 20, 2006 Share Posted July 20, 2006 use a regular propane torch with the tip on it and all, the venturi in it mixes the exact right amount of air with the propane for the best combustion. i made a small bore one out of an empty coleman propane tank as the combustion chamber(danger will robinson danger) and welded some pipe and a sparkplug to it it fires AA batteries nicely :) Quote Link to comment Share on other sites More sharing options...
degoba Posted July 20, 2006 Share Posted July 20, 2006 How about a gauss rifle. I am really wanting to build a larger version of whats posted below, and seeing if I can take down small animals. http://sci-toys.com/scitoys/scitoys/magnet...ifle/slomo5.gif Quote Link to comment Share on other sites More sharing options...
dirty D Posted July 21, 2006 Share Posted July 21, 2006 not a chance, guass rifles are weak, especially the kids ones with permenent magnets. electromagnetic ones need a huge amount of power with complex electronics for timing and many stages to build up a good amount of velocity. railguns are a lot more powerful but also need a huge amount of power.
